One of my 3d print model has been reported and I don't know why.

For 15 million dollars, you wouldn't have to. lol.

It could be the person selling the yacht, the manufacturer or another artist that could have reported you. I'd contact support to find out more. They might be investigating the claim to see if it "holds water" before contacting you.

You'd probably have to change it significantly before re-uploading it.

Turns out it was reported by someone who purchased the model and don't understand something.
:(
